TLDR
Recommendations are made to improve the control of aerosol-transmitted infections in hospitals as well as in the design and construction of future isolation facilities.
Abstract
Summary The epidemics of severe acute respiratory syndrome (SARS) in 2003 highlighted both short- and long-range transmission routes, i.e. between infected patients and healthcare workers, and between distant locations. With other infections such as tuberculosis, measles and chickenpox, the concept of aerosol transmission is so well accepted that isolation of such patients is the norm. With current concerns about a possible approaching influenza pandemic, the control of transmission via infectious air has become more important. Therefore, the aim of this review is to describe the factors involved in: (1) the generation of an infectious aerosol, (2) the transmission of infectious droplets or droplet nuclei from this aerosol, and (3) the potential for inhalation of such droplets or droplet nuclei by a susceptible host. On this basis, recommendations are made to improve the control of aerosol-transmitted infections in hospitals as well as in the design and construction of future isolation facilities.

A Review of the Research Literature on Evidence-Based Healthcare Design

TL;DR: This review found a growing body of rigorous studies to guide healthcare design, especially with respect to reducing the frequency of hospital-acquired infections and the state of knowledge of evidence-based healthcare design has grown rapidly in recent years.
Journal ArticleDOI

Transmission of COVID-19 virus by droplets and aerosols: A critical review on the unresolved dichotomy.

TL;DR: It is demonstrated that the nosocomial transmission by airborne SARS-CoV-2 viral-laden aerosols in healthcare facilities may be plausible and clearly defined, science-based administrative, clinical, and physical measures are of paramount importance to eradicate the COVID-19 pandemic from the world.
Journal ArticleDOI

Violent expiratory events: on coughing and sneezing

TL;DR: In this paper, the authors present the results of a combined experimental and theoretical investigation of the fluid dynamics of such violent expiratory events, which reveals that such flows are multiphase turbulent buoyant clouds with suspended droplets of various sizes.
Journal ArticleDOI

Recognition of aerosol transmission of infectious agents: a commentary

TL;DR: This review considers the commonly used term of ‘aerosol transmission’ in the context of some infectious agents that are well-recognized to be transmissible via the airborne route, and discusses other agents, like influenza virus, where the potential for airborne transmission is much more dependent on various host, viral and environmental factors, and where its potential for aerosol transmission may be underestimated.

The fluid mechanics of natural ventilation

TL;DR: In this paper, two forms of ventilation are discussed: mixing ventilation and displacement ventilation, where the interior is at an approximately uniform temperature and there is strong internal stratification, respectively, and the effects of wind on them are examined.

Incidence of common respiratory viral infections related to climate factors in hospitalized children in Hong Kong

J. W. T A Ng
TL;DR: Hong Kong has a subtropical climate and an influenza seasonality lying approximately mid-way (March-June) between those of the Northern (November-March) and Southern (June-September) hemispheres as discussed by the authors.

Infection Risk of COVID-19 in Dentistry Remains Unknown: A Preliminary Systematic Review

TL;DR: It seems that there are almost no reported cases of infection by SARS-CoV-2 during dental treatments, occupational or nosocomial transmission could not be ruled out, and further prospective assessment of COVID-19 transmission is urgently required.
Journal ArticleDOI

PAP therapy increases the risk of transmission of COVID-19.

TL;DR: Medically prudent recommendations have been established for home use of PAP therapy in asymptomatic patients and patients with suspected or confirmed COVID-19 and the emergency use ofPAP devices as a substitute for ventilation.

outbreak of invasive pulmonary mycosis in neutropenic hematologic patients in relation to remodelling construction work

TL;DR: An elevated number of fungal spores found in samples from the hematologic hospitalization area as well as no further new cases being reported following the transfer of the patients suggest that the outbreak was related to the adjacent construction work being carried out.

Forensic implications of respiratory derived blood spatter distributions

TL;DR: The nature of blood aerosols produced in physiological studies of an upright subject expiring small volumes through straws, spitting and mouthing sounds, and a semi-prone subject spitting through a bloody mouth or snorting through a single nasal orifice and by a simplified physical model of the respiratory system were investigated.
